摘要： 测量活度的方法很多,等蒸气压法是其中的主要方法之一,我们根据等压法原理设计和安装了一套较简单的实验装置,测量了焦磷酸钾在不同浓度水溶液中的平均活度系数和渗透系数,结果与文献[1]相符,证明实验装置合乎要求。

Abstract: A simple instrument for measuring activity coefficients and osmotic coefficients of electrolytic solution was installed by the isobaric principle. Using the method of double standard solution, activity coefficients and osmotic coefficients of K4P2O7aqueous solution were determined.The results are in close agreement with literature value.
